The better aero of cars in your example make up for difference in power. Engine TYPE has absolutely NOTHING to do with top speed, except how it may effect frontal area and ultimate power output...This is interesting. My brother and one of my friends both have '91 Acura Integra GS, and they will both climb past 210 stock. How is it that an inline 6 goes slower than a inline 4 (non-vtec). Not trashing inline 6 motors (I have a 7MGTE), but wtf? Don't let any Honda fans in on this, lol.
EDIT: Come to think of it, my '91 Celica is governed at 190kph (117mph), but it climbs up to that speed really fast.
MKII top speed was documented during actual product run, by multiple media sources, back when they verified Manufacturers data independently. Its 125-135 MPH, depending on year/gearing, with the fastest speed recorded by Car and driver in an 84, IIRC. They used a mechanical add on wheel with a calibrated speedomeder/odometer combo.i dont think these are the top speeds of the cars, but the fastest people have gone.
